摘要

采用NRZ编码格式的伪随机脉冲序列对垂直腔面发射激光器(VCSEL)在抽运电流调制下的工作动力学进行了数值模拟。结果表明，对于某些激光参数和调制参数，由于侧模的激发延迟，发射脉冲的模组成与主模的激发有很大的不同。我们认为这一结果对于应用和VCSEL在现代基于光纤的电信系统中的使用是重要的。

Mode transformation in VCSEL emitting pseudorandom sequence of pulses

The dynamics of vertical cavity surface emitting laser (VCSEL) operation was numerically simulated under the pumping current modulation by pseudorandom pulsed sequence for the NRZ encoding format. It was obtained that, for certain laser parameters and modulation ones, the emitted pulses have substantially differing mode composition due to delay in exciting the side modes with respect to the main mode excitation. We consider this result to be of importance for applications and to be taken into account with the VCSEL's use in modern optical-fibre based telecommunication systems.
